The invention relates `to that class of ;shellers in 7 which aspikedcylinder, not unlike that `cfa` thrashing-machine, is employed,incombinationwith' a ribbed l, concave, forthe Apurpose ot' removingfthe .corn from the cob, andconsists in First, a concave, havingrows orribs placed alterl natelyo'n different, diagonal lines, combined with acylinder, having its-teeth placed in curved lines, the outer ends ofsaid curves occupying a forward posi- :tiouwith reference to thedirection in which the cylinder revolves. .y n Second, 'i'n formingasupplemental chamber in l `front of the cylinder and hopper, into whichthe corn l w ,isthrown by the centrifugaljforce of the cylinder,` andfrom which it (thecorn) falls upon the riddle, but is not allowed torebound and be again 'carried around- `between the cylinder andtheconcave, whereby-much' of it would be broken. y Third, an elastic.`cir-yielding4 iap` or apron, formiing part o f, or attached to thethroat in the bottoni of the hopper, through whichthe ears of corn pass,the object of the apron being to prevent the `escape jof loose kernelsocornwhiclrarethrown from the revolvingcylinder. Y

AZ is a girt connecting thefupper ends of .the two parts `at the rear ordischargingendof the machine.l

. B is a cylinder, constructed substantially like those in general usein this class of shellers. The teethon `thislcylinder are not placedinrows whichrun straight across on linesparallel with its axis, but areplaced in curved lines, vthe center oflwhich recede, assuming that thecylinder runsy in .the direction .indicated by the arrows in iig. 4.

supported, ,by means of aframc-work or other suitable construction, at.the front end of the machine.

p B' is a pulley or bandwheel,keyed to shaft l1.

"h, withsides A1, form` the i'amework -which supports the working partsof the sheller.

nountedupon shaft b, which isI C is a concave formed in the arc of acircle, and adjustablyfsupported at a properdistance below cylinder B.This concave may be castwin one piece, though, for convenience, Insuallyprefer to make it in sections, as shown in iig. 3. .-.Eachxofthese sections is armed with a nuinbe'rof ribs, c, placed' on lines`diagonal to the` edges of said sectionsfAll of the ribs` onone sectionare not, however, parallel with each other, but are arranged asfollows:The two nearest the center are placed atan angle of about thirty degreesto each other, and then the remaining ones are placed parallel to theone to which they are contiguous, on either sideof the center.4 Inalternatesect-ions, the arrangement of ribs should be` relativelyreversed, so that, in concaves composed of three sections, the positionoccupied by the ribs would be substantially that` represented in gD isa. hopper-box, of a squareV or rectangular-form, having a throat, d,through which the corn is fed to the cylinder. l

I)l is an elastic wing orapron, forming one side lot' 'saidthroat,rbeing constructed so as to yield, for a purpose which will behereinafter explained.

A partition, D2, divides the lower part of this )hopper-box into twochambers, one of which "may, be called the cylinder-chamber, andtheother the deflecting-chamber. Y A' 'Immediately iure-ar of the cylinderis placedl the `separator,'the front end of which is represented as beinVsuspended from the concave, while the rear end is a justably suspendedfrom girt A2, by means of pins aand straps a'.

The bottom of the separator is made of bars or ro`dsE, runninglengthwise from end to end,`and are supported, at two or moreintermediate points, by being passed through cross-bars E', having theirends attached to the vsides of the separator, as is clearly shown iniig. 1.

A vibratory motion is imparted to the separator by means of bell-crankF, which is in turn operated by pitman F1, from crank-wheel F2, -bo'thbeing shown in dotted lines in iig.' 1.

G is a chute-board, placed in an inclined position below the separator,and extending from the rear end of the sheller to its front end, asiniig. 2. l

I usually prefer to provide the central portion of this chute-board withperforations,as shown in the drawing, but this inaynot be essential.

A K K-are arms projecting from the rear endjof the sheller;

.t Maa adam... ,e

k k are rollers mounted in said arms; and

K' .is an endless carrying-apron or belt; passing around rollers k, andactuated by them.

The operation of my machine islas follows:

Motion being communicated to cylinder B by hand or other power, the cornisr` fed through thev hopper, the yielding apron or wing Dl bending downfar enough to permit the ear to pass through the throat.

After passing the throat, the ear is carried around between the cylinderand the concave, where, owing to the peculiar arrangement of the teethand ribs upon the parts, the corn is entirely removed from the cob. Y

The corn and cobs are then thrown iup into the chamber formed inthe rearend of the hopper-box, and then falls upon the separator, where thercornand cob are divided, the corn passing down the chutehoard, and thenceout at the front of theomaohine, while the cobs are carried over therear end of the separator onto the endless apron, which deposits them ata convenient distance from the machine, or, by elevatingthe outer end ofsaid apron sufficiently, the cobs may be loaded upon a wagon. l

lVhen the corn and cobs are thrown from the concave into thedeecting-chamber, there would more or less of it rebound onto thecylinder, and be carried around through the concave again, which wouldbreak a port-ion of the corn; besides which, the cobs would interferewith the proper shelling of the ears just introduced; but, by means ofthe partition D, this return of corn and cobs is wholly prevented.

While the corn is passing from the separator or 4riddle down to and overthe chute G, it is subjected to the action of a blast from the fan I,for the purpose of removing all eha'and other impurities.

llie transverse bars E allow the eobs to pass readily over them, butcheck the movement of the corn, whereby it (the corn) is'compelled topass through the riddle.` Thus a perfect separation is ei'ected.

Having now described my invention,

What I claim as'new, and desire to secure by Let ters Patent, is'- l 1.In the corn-Sheller herein described, the throat, provided with theyielding ilaps or wings D1 d, (one or botb,) for the purpose of feedingthe ears of corn longitudinally, as set forth.

2. In the corn-Sheller, the concave C, provided with rib's c, arrangedin sections on diagonal lines, with the angle of presentation onalternate sections reversed, in combination with the shelliug-oylinderB, provided with teeth, arranged in curved lines, substantially as setforth.

3. The coinbinatiomin a corn-Sheller, of the hopper, provided with theelastic throat Dl dl, the deflecting-ehamber, as described, theshelling-cylinder B, and concave C, arrranged and operatingsubstantially" as set forth.
